Application filed April 2, 1900. Serial No. 11,208. (No specimens.)

To all whom, it may concern.-

Be it known that I, WILLIAM N. RUMELY, a citizen of the United States, residing at La Porte, La Porte county, Indiana, (post-office address, La Porte, Indiana,) have invented certain new and useful Improvements in Antifriction Alloys, of which the following is a specification.

My improved antifriction alloy is formed of lead, tin, antimony, nickel, and phosphortin, united by fusion. The best proportions of the component parts are: lead, about seventytwo parts; tin, about fifteen parts, the lead and tin together forming eighty-seven parts; antimony, twelve parts; nickel, .75 part; phosphor-tin, .25 part. The phosphor-tin employed is for the purpose of getting about .0175 part of phosphorus into the alloy, and this will be accomplished by using .25 part forth.
